The bank of internal combustion engines is not shown. The apparatus includes a gear train or mechanism for operating certain elements thereof. The said gear mechanism has as a part thereof, an operating shaft which is driven from a suitable driving connection, not shown between it and the bank of engines. The apparatus is shown by way of example for the adaptation thereof with a bank of four engines, but it is to be understood that it may be set up in'a manner whereby it may be employed in connection with a bank of engines of a smaller or greater number of engines.

The gear train or mechanism (Figure 2) includes the operating shaft referred to indicated at I, a pair of gears 2, 3 carried by shaft l, a gear 4 meshing with gear 2, a pair of intermeshing gears 5, 8, the former meshing with gear 4 and the latter with gear I, a gear 8 meshing with gear to meshing with gear 9 The gears are of 0 the desired ratio with respect to each other for the purpose of operating those parts or elements driven therefrom at the desired speed. The gears which gears 5, 6 are mounted are designated l I, I2

' respectively. The gears 9,- I 0 are of like diameter but of smaller diameter than the gears 2, 5, 6. The, gear 9 is mounted on a shaft I3. The gear I0 is mounted on the shaft 14 01' a driving means for a combined pump and strainer structure l5 which will be presently referred to. The gear 2 is of less diameter than gear 1. The latter is the larger of the gears and it is connected to the operating shaft iii of a fuel' charge disu tributing mechanism ll (Figures 2 and 5 to 7) to be hereinafter referred to. The gear 4 is of slightly greater diameter than gear 8 but of slightly less diameter than gear 3. The shafts upon which are mounted gears 4 and 8 are designated I9, 20 respectively. The gears 2, 3 are termed drivers, the former is employed for operating the fuel charge distributing mechanism 11, andthe latter for operating the driving means for the combined pump and strainer structure I5. The shaft l is termed a cam shaft acting to rotate the cam 2| (Figure 1) which is employed for setting and releasing a fuel expelling structure 22 (Figure 2) to be referred to for successively forcing charges of fuel into the distributing mechanism 1. The cam 2| also functions to open an intake valve mechanism to be hereinafter referred to.

The gear train or mechanism is supported from an upstanding plate 23 including a horizontal part 24 and avertical part 25. The plate 23 is formed throughout its edges with a pair of spaced inwardly extending endless parallel flanges 26, 21 (Figures 2, 3 and 5).

The apparatus includes a housing 28 (Figure 1) formed of a cylindrical upper part 29 and a rectangular lower part 38 offset with respect to part 29. The parts 29, 38 are separated, at their points of mergence, by a web 3| which in connection with said parts forms the housing 28 with upper and lower compartments 32, 33 respectively. The web 3| has an enlarged opening 34 for establishing communication. between said compartments. The plate 23 is anchored against one side of housing 28. The part 25 thereof extends upwardly from one end of housing part 38. The part 24 of plate 23 opposes and extends laterally from the other end of housing part 38. The body of housing part 29 is formed with a vertically disposed channel 35 opening at the top edge of such body. The housing 28 is formed with a socket 36 positioned in the lower portion of housing part 29 and in the top portion of housing part 38. The socket 36 opens into compartment 33. The lower end of channel 35 communicates with socket 36 through the base of the latter. The top portion of housing part 38 is extended laterally from the lower portion of housing part 29 to provide a seat 31.

Seated upon, as well as being anchored to and extending across the top of housing 28 is an annular block 38 (Figure 1) formed with a radially disposed chamber 39. The inner edge of block 38 is shouldered, as at 48: Seated on, anchored to, and extending into the block 38 is a tubular plug element 4| formed of an outer, an intermediate and an inner part 42, 43 and 44 respectively. The part 42 is of greater diameter than part 43 and the latter is of greater diameter than part 44. the parts 43, 44 are arranged within the block 38. The element 4| has its inner edge upon three different diameters, as at 45, 46 and 41. The junction of the inner edge portions form shoulders eter than edge portion 46, and the latter is of greater diameter than edge portion 41. The edge portion 46 is arranged between the edge portions 45, 41. The edge portion 46 has its inner part beveled, as at 48 to provide a valve seat for a valve 48. The edge portion 46 forms a valve chamber for valve 48-. The edge portion 45 is threaded for a purpose to be referred to. The edge portion 41 forms a fuel charge outlet passage and receives the stem of valve 48. Threadedly engaging with the edge portion 45 is an intake head and coupler element 58 for the inlet end of a fuel charge conducting line 5| which leads to and communicates with the fuel charge distributing mechanism 1. The element 58 comprises a peripherally threaded body 52 of circular cross section formed with a peripheral flange 53 abutting the plug element 4|. The body 52 at its outer portion is formed with an internal chamber 54 for the fuel prior to the entrance of the latter into the line Extending through the body 52 is a plurality of inclined spaced parts 55 which establish communication between the valve chamber formed by edge 46 and the chamber 54. The outer end wall of the chamber for valve 49 is provided by the inner end of body 52. The line 6| extends into chamber 54 and is encompassed by a compressible packing 56 which seats on body 52 and projects into the outer end of chamber 54. The line 5| is anchored to the body 52 by the cap member 51 threadedly engaging with the body 52 5 and coacting with the packing 56. The holdfast means for the block 38 are indicated at 58. The holdfast means for element 4| are indicated at 59. The said means 58 and 59 are shown in Figure 4 Arranged within the compartments 32 and 33 is the intake and expelling mechanism -22 which functions to receive the fuel from the intake valve mechanism to be referredto and to expel the fuel therefrom in successive charges into the line 5|. During the intake of fuel into the mechanism 22 the latter is closed to line 58. 'The mechanism 22 includes a sleeve or cylinder 6| open at each end, and at its outer end is peripherally flanged as at 62. The cylinder 6| extends through the block 38, and depends into the compartment 32. The flange 62 seats upon shoulder 48. The part 44 of theelement 4| extends into and snugly fits the inner face of the outer portion of cylinder 6|. The portion 43 of element 4| bears against the flange 62 when 25 element 4| is anchored in position for clamping the cylinder toblock 38. The inner end of cylinder 6| is spaced from the web 3|. The cylinder 6| in connection with the element-4| provides a plunger chamber 62 for a reciprocatory plunger 63 functioning to draw a fuel charge into and to expel it from chamber 62. The cylinder 6| is formed with a slot 64, the outer wall of which is in very close proximity to the inner terminus of element 4|. The slot 64 forms an intake for chamber 62. The inner edge portion 48 of element 4| provides an outlet for chamber 62 and such outlet is controlled by valve 49.

The plunger 63 is of a length to extend from the open or inner end of cylinder 6| into the 40 compartment 32, and adjacent such inner end the plunger 63- is formed with a peripheral annular flange 65. Between the flange 65 and the inner end of plunger 63, the latter has mounted thereon an annular member 66 forming in connection with the plunger an upwardly opening socket or pocket 61. The lower face of member 66 is formed with a pair of diametrically disposed depending rounded lugs 68, only one shown. Surrounding theplunger 63 and extendr ing into pocket 61 provided by plunger 63 and member 66is a coiled spring 68. Arranged within compartment 32 surrounding the cylinder 6| and the plunger 63 and extending inwardly of the cylinder is a combined controlling spring compressing and plunger shifting element 68 formed of a sleeve-like body 68 provided at its outer end with an outwardly directed annular flange 18. The inner end of body 68 is provided with an inwardly extending annular flange 1| which coacts with the flange 65 to provide the fuel expelling stroke for the plunger. The flange 1| bears against the outer end of spring 68'. The controlling spring for the mechanism 68 is designated 12, surrounds the body 68 and is interposed between the flange 18 and web 3|.

That part of plunger 63 below the lugs 68 is flattened, as at 12' and carries a pair of polygonal shaped abutment members 13 on each side thereof, only one being shown. Supporting means for the members 13 is indicated at 14 and is secured to. part 12' of plunger 63. The members 13 form elements of a cam operated shifting device for imparting intermittently a suction stroketoplunger 63 against the action of the spring 12.

The cam operated shifting device also includes a plunger shifting member 75 formed of an intermediate part it and a pair of oppositely ex= tending end parts ll, I3. The former is of less length than the latter, bifurcated and is provided with a pair of depending, spaced outwardly inclined noses F9. The part 78 is bifurcated, straddles the part 72' of plunger 63, seats on opposed parallel faces of the members 13 and bears against the lugs I58. The intermediate part "it :of the shifter member I5 is eccentrically mounted on an eccentric shaft 80 which is journaied in and extended from one side of housing 22. The shaft 80 on its projected end carries a gear wheel 9| (Figure 2).

The cam 2| is rotatable and employed for intermittently operating the cam operated shifting device. The cam 2| functions during each revolution thereof to coact with the noses 79 for the purpose of lowering the part it twice at spaced intervals. The cam 2| is formed with a pair of oppositely disposed working surfaces 92,

83 of like length which gradually rise and terminate into a pair of oppositely disposed lobes 84, 85 respectively. The noses I9 travel against the working surfaces and these latter coact with the noses l9 for the purpose of intermittently elevating part 71 and lowering part it until the nose passes off the lobes. When part i8 lowers it will coact with the members I3 and impart a suction stroke to plunger 63 against the action of the controlling spring I2. .The direction of movement of the plunger 63 on the imparting of the suction stroke thereto is towards compartment 33. As the plunger 33 moves in such direction the flanges 68 and II will coact to move the element 68 towards the web 3| and store up tension in or compress spring I2. When noses I9 passes off a lobe the spring I2 will be free to act on flange I0 to shift the element 68, and the flanges 65 and II will coact due to the expanding action of spring I2 to impart an expelling stroke to the plunger 63.

The inlet valve mechanism which is associated with the plunger chamber 62 is generally indicated at 86 and it is positioned within and extended outwardly from the chamber 39 of block 39. The chamber 39 is closed at its inner end and open at its outer end. The block 38 is formed with an inclined outlet port 09 which registers with the slot 54 formed in the cylinder iii. The port 89 extends through the shoulder '30. Extending into and threadedly engaging with threaded wall 0? of the chamber 39 is a housing 90 including a plug shaped body 9! having a flaring outlet 92 at its inner end, an annular inlet 93 at its outer end, an axially arranged channel 95 connecting said inlet and outlet, a pair of oppositely extending spaced endwise aligning tubular parts 95, 96 disposed at right angles to channel 94 and a diametrically disposed valve chamber 9'I, intersecting channel 94 and having its wall forming fiush continuations of the inner faces of the parts 95, 95.

Mounted in the chamber 97 is a cam actuated spring controlled reciprocatory vertically disposed valve 98, of a circular cross section and formed intermediate its ends with an annular groove 99 for establishing communication between the outer and inner portions of the channel 94. The lower end of valve 98 merges into an elongated valve stem I00 which extends down through channel 35 and depends below socket 36 to permanently seat on cam 2|. The stem I00 is formed with an annular flange I0| positioned in socket 35. interposed between the flange IOI and the base of socket 36, as well as surrounding stem I00 is a coiled spring I02. Threadedly engaging with the wall of socket 38, as well as depending from the latter is a peripherally thread- 5 ed guide 503 for the lower portion of stem I00. The guide 903 is peripherally shouldered, as at I04 for the purpose of abutting the lower face 7 of the top of part 30 of housing 28. The cam 2| is of a length whereby its surfaces 82, 83 and 10 lobes 84, 85 will provide for the seating thereon of stem H00 and the noses I9. Arranged within the tubular part 95 is a coiled controlling spring I05 for valve 90. 'Ifhreadedly engaging with the interior of the tubular part 95 for closing the upper end of the latter is an abutment plug I06. The valve 98 is formed with a socket I 01 in its upper end. The spring I05 abuts the inner end of plug I06 and extends into and abuts the base of socket 901. The flaring outlet 92 coacts with the chamber 39 to form a fuel receiving space I08 from which extends the port 89.

The combined pump and filtering structure I5, which may be of any suitable construction is mounted on a base plate I 08 and is positioned upon the seat 39. The structure I5 constitutes a fuel filtering and supply pump element which sucks the fuel out from a reservoir or tank, not shown and feeds it, after it has been filtered, through the supply line I09 to the intake valve mechanism. The line |09 opens and extends into the intake 93 (Figure 1). Encompassing line I09 and extending into intake 93 is a compressiblepacking I I0. Threadedly engaging with the valve housing 9|, bearing against the packing H0 and 35 encircling line I09 is a securing cap III for the latter.

With reference to Figures 1, 5, 6, 7 and 10 to 12. The fuel charge distributing mechanism H includes an open top housing 2 formed of a bottom II3, an end wall II4, an inner side wall II5, an outer side wall I I6 and an outer end wall I I5. The top of the housing I I2 is closed by a removable plate i I6. The end wall I I4 is formed with a pair of spaced openings I I1, I I8, the former being 45 arranged rearwardly of and above the latter. The end. wall I I5 is arranged inwardly with respect to the outer ends of the walls I I 5, I I6. The inner side wall H5 in proximity to and outwardly with respect to wall I i5 is formed with a vertically disposed slot l I9. The outer side wall I I6 is formed with an opening 920 in proxmity to its top and between its vertical meridian and the wall i I4. The outer side wall II It is also formed in close proximity to the bottom Il3 with a row of equi-distant 55 spaced side-wise aligning openings I2I. The walls of openings i20, I2i are threaded. Integral with the inner faces of the walls I I 5, I I5 and above the openings I2I is a series of equi-distant spaced transversely extending webs I22. In- 60 tegral with the inner faces of the walls II 4, H5 and H6 and with the inner faces of the walls H4, H5 and H6 are webs I23, of less width than either of the webs I22. One of the webs I23 is spaced from the inner web of said 65 4 series of webs I22, and the other web I 23 is spaced from the outer web of the series of webs I22. The webs I22, I23 are formed with endwise aligning openings I25 which endwise align with the opening H8. The wall 5' is formed with a 70 pair of spaced openings I24, I25 which align with the openings I24, I 25 respectively. Journaled in the aligning openings 1, I24, I24 is the operating shaft I6 for the said mechanism IT. The shaft I6 operates in a counter-clockwise di- 75 of the latter.

rection, extends beyond wall H4 and is journaled (Figure 5) in the part 24 of plate 20. As hereinbefore set forth the shaft I6 is connected to gear 1 thereby on the operation of the latter, the shaft I 6 will be driven. Journaled in the aligning openings II3, I25, I is a composite shaft I26 connected to an adjusting device therefor. The said device is to be later referred to. The shaft I26 projects beyond the wall H5. The shaft I6 terminates within the opening I24 in wall I I5.

Fixed to the shaft I6 between the webs I22 and between each end web I22 and a web I23 is a set of actuating cams I21 corresponding in number to the number of and arranged above the openings I2I. The cams I21 are of like construction, and each includes a radically disposed lobe I26 having an inclined side face I23 and a straight face I30 disposed ina plane parallel to the diametric center of the cam The lobe I28 is of tapered form having a working terminus I 3I.

The shaft I26 constitutes a combined carrier and control for the shifter members, to be referred to, for the fuel charge outlet valve mechanism. The shaft I26 is formed of an adjustable elongated bar I32 of a length to project from the wall 5'. Fixed at spaced intervals lengthwise of bar I32 are short cylindrical members I33, each formed with a bore I33 eccentrlcally disposed with respect to'the axis thereof. The members I33 are journaled in the openings II3, I25, I25 and have their ends flush with the ends of the latter.

The fuel charge outlet valves for the mechanism I1 are designated I34 and correspond in number to the number of the openings I2I. The valves I34 are of like construction, and but one will be described. Each outlet valve I34 comprises a tubular plug I34 having two parts of different inner diameters as indicated at I35, I36. The lug I34 is peripherally threaded and formed with a peripheral shoulder I31 intermediate the ends of its peripheral threads. The plug I33 threadedly engages with the wall of an opening I2I and has its inner end flush with the inner face of side wall II6 ofhousing II2. When plug I34 is secured to the latter, a locking nut I38 is interposed between shoulder I31 and wall H6. The part I35 is of smaller inner diameter than the I 36 and forms a passage for an extension I33, and a bearing for a stem I40 secured to the inner end of the extension I33. The stem I40 projects outwardly from a beveled valve member "I The stem I40 is substantially of cruciform cross section. The extension I39 is of circular cross section and projects beyond the outer end of plug I34. The part I35 of the plug I33 is the rear part of the latter, and has its rear edge beveled, as at I42 to provide a seat for the valve member I H which is arranged inwardly of the rear end of plug I34. The stem I40 projects from the forward side face of valve member I H and has its lengthwise edges spaced inwardly from the edge The rear side face of valve member I has formed integral therewith, diametrically thereof, the shank I43 of a T-shaped pull member I44 which projects rearwardly into the housing H2. The head of member 4 is designated I46 and has its forward edge portions rounded 'as at I46. The outer end of the extension I33 carries a stop I41 for coaction with the outer end of plug I33 for arresting the inward shift of the valve member I when the pull member I44 is moved rearwardly by a means to be presently referred to and also to compress a controlling spring -I41'. which surrounds the extension I33. The

spring I 4'! acts to maintain the valve member I normally closed and it is interposed between the stop I41 and the shoulder provided by the juncture of the two inner diameters of the plug I34.

There is associated with each pull member I44 a shifting member I48. Each member I48 is mounted upon the bar I23 between the ends of a pair of opposed members I33. The shifter members I46 are operated from the cams I21 on the shaft I6. The cams I2.1 are so disposed on shaft I6 as to provide for the successive operation of the members I43 resulting in the successive operations of the engines. The latter may be operated simultaneously by positioning the lobes of the cams I21 in sidewise alignment. Each member I48 (Figure 12) comprises a block I43 having its lower portion bifurcated to provide a pair of arms I53 which straddle the shank I43 of a pull member I44. The block I43 between its transverse median and its upper end is formed with an opening I5I for the purpose of mounting it upon that portion of the length of bar I23 between a pair of webs. The normal tendency of each shifting member I43 is to position the lower portion thereof to extend rearwardly with respect to shaft I26. The rear side of block I 43 is formed, near its top with a transverse groove I62 for receiving the outer end of the lobe I28 of a cam I21 whereby on the operation of shaft I6 the lobe I28 will ride upwardly against the rear of a member I48 and enter groove I52. The wall of the groove J52 coacts with the outer end of the lobe of the cam to provide for the lower portion of the block I43 swinging rearwardly against the edge portions I46 of head I causing the member I44 to move rearwardly exerting apull on valve member I 4|. to move it to open position to enable a fuel charge to pass into the plug I34. The shifting of the lower portion of member I48 is had against the action of the spring I41 and when the lobe clears the groove I52 the spring I41 will cause the seating of valve I H to close plug I 34.

Coupled to and extended outwardly from the outlet valves I34 are spring controlled intake valve mechanisms I53, which are attached to the intake ends of the fuel charge feed lines I54 leading to the cylinders of the engines of the bank. Each mechanism I 53 includes a hollow casting I55 formed therein with a socket I56 at its inner end, a valve chamber I51, avalve seat I 58 at the rear end of chamber I51, a passage I53 connecting socket I 56 to chamber I51 and a socket I60 into whichchamber I51 opens. Ar-

ranged within chamber I51 is a valve member 55 latter. When casting I55 is connected to plug I34, the shoulder I31 on the latter abuts the inner end of the casting. Extending into socket I60 and threadedly engaging with the walls of the latter is 'a peripherally threaded plug I84, formed intermediate the ends'of the threads thereon with a peripheral shoulder I35, which when plug I64 is connected to casting I55 abuts the outer end of the latter. The inner end of plug I64 provides the outer end of valve chamber I 51. The spring I62 is arranged between the inner end of plug I64 and the valve member m. The plug 164 is provided witha plurality of outlet ports I61, an axial channel I68 and a socket I89. The ports I 61 are inclined towards each other, extend from the inner end of the plug and open into the inner end of channel I98.

The outer end of the latter opens into socket' I89. Extending into the latter is a fuel charge feed line I54. Encompassing the latter and projecting into the outer end of the socket IE9 is a compressible packing I10 and threadedly engaging withthe plug I64 is a securing cap I1I for line I55.

The fuel charge conducting line 5I is coupled to and communicates with the fuel receiving chamber I12 provided by the housing H2, and for such purpose a coupling device I13 is employed, which consists of a peripherally shouldered sleeve I14 which extends into and threadedly engages with the wall of opening I20. The sleeve I14 is-formed of two different inner diameters. The part of smallest inner diameter is at the outer portion of the sleeve and extending into such part is the line 5|. Encompassing the latter and extending into the outer end of sleeve I14 is a compressible packing I15. Mounted on the line 5I bearing against the packing I15 and threadedly engaging with the sleeve I14 isa se- 4 curing cap I16 for line SI.

-' therefor.

The shifting member 15 is capable of being adjusted for varying the length of the suction stroke of plunger 63. The shifting members I48 are capable of being adjusted for varying the extent of the opening movement for the. valve I. The adjustment of members 15, I48 is had simultaneously and for such purpose an adjusting device I11 common to said members 15, I48 is employed. The device includes a train of intermeshing gears consisting of the gears I18, I19, I80 andthe gear 8|. The gear I18 is of greater diameter than the gears I19, I80 and 8|. The gears I19, I80 and 8| are of like diameter. The gear 8| meshes with gear I18, the latter with the gear I19. The gear I80 meshes with gear I19 and is fixed to the bar I32 of the shaft I26 and extends through slot H9. -The gears I18, I19 are carried by shafts I8I, I82 respectively. The gear 8I is eccentrically" mounted on shaft 80.

When gear 8i is shifted from gear I18 and depending on the direction of the shift of gear 8!, the shaft 80 is elevated or lowered carrying element 15 therewith, thereby varying the period of contact of nose 19 with cam 2 I. By this arrangement the stroke of plunger 63 may be adjusted. When gear I19 is shifted from gear I18 and depending upon the direction of shift of gear I19, the latter will shift gear I80 which is connected with shaft I26. The gear I80 when shifted will carry shaft I26 therewith and provide for the latter varying the position of the lobes I28 relatively to the shifting members I48. The varying of the position of the lobes I28 relative to members I48 enables an adjustment. to vary the extent of the opening movement of valves MI. Attached to the shaft I8I is a shifting lever I83 The shafts I8I, I82 are journaled in housing 22.

The shaft I is extended from housing part 30 and plate 24 and has mounted thereon spaced packing glands I84, I85 respectively engaging with a wall of housing part 30 and with the plate 24. One end of the shaft I carries a drive pulley I88 therefor which is operated from a driving connection, not shown, leading from the bank of engines. Connected to shaft I adjacent housing part 38 is governor I81 preferably of the form shown in copending application Serial No.

731,207 filed June 18, 1934. The purpose of the governor I81 is to prevent the operation of the actuation of member 15 from cam 2i when the engines reverse thereby preventing the impairment of the cam 2I and member 15. The foregoing statement also applies to the stem I00 of the valve 98 which forms an element of the intake valve mechanism for the cylinder 8|.

The shifting device I11 controls the intake and output of the liquid fuel simultaneously. The cam 2| provides for the operation of member 15 and valve stem I00 in a manner whereby the valve 98, will close before the plunger 83 starts its expelling stroke.
